Isopiestic determination of the osmotic and activity coefficients of {yK(2)HPO(4) + (1-y)KH2PO4}(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2020)
Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 ...
Ecological Risk Assessment of Heavy Metals in the Soil at a Former Painting Industry Facility
(Frontiers Media Sa, Lausanne, 2020)
Soil samples from the site of the former largest paint and varnish factory in ex-Yugoslavia were analyzed for arsenic and eight heavy metals (Pb, Cd, Zn, Cr, Ni, Cu, Fe, and Hg). Several additional soil properties (pH, ...
Enhanced Interface Adhesion by Novel Eco-Epoxy Adhesives Based on the Modified Tannic Acid on Al and CFRP Adherends
(MDPI, Basel, 2020)
This paper presents a new process for obtaining eco-epoxide adhesives synthesized from bio-renewable raw material (tannic acid-TA) and used for bonding lightweight materials (aluminum (Al) and carbon fiber reinforced polymer ...
Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Oxidative degradation of Acid Blue 111 by electro-assisted Fenton process
(Elsevier, Amsterdam, 2020)
The degradation of Acid Blue 111 anthraquinone dye has been studied by the simple electro-assisted Fenton process and the obtained results were compared to the Fenton process. Ferrous sulphate and hydrogen peroxide were ...
Improvement of lignocellulosic biomass conversion by optimization of fungal ligninolytic enzyme activity and molasses stillage supplementation
(Springer Heidelberg, Heidelberg, 2022)
Fungal treatment of lignocellulose is an ecologically and economically acceptable method. However, it needs improvement to increase the hydrolysis rate. A novel combination of multiple response optimization of ligninolytic ...
Morphology, Structure and Mechanical Properties of Copper Coatings Electrodeposited by Pulsating Current (PC) Regime on Si(111)
(MDPI, Basel, 2020)
Copper electrodeposition on (111)-oriented Si substrate was performed by the pulsating current (PC) regime at various average current densities in the range of 15-70 mAcm(-2), obtained by varying either the frequency (30, ...
Microstructure and cavitation erosion performance of nickel-Inconel 718 composite coatings produced with cold spray
(Elsevier Science Sa, Lausanne, 2020)
The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the ...
Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Journal of Electroanalytical Chemistry, 2021)
Hydrated iridiumoxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
